SHARPENER FOR HAIR-CLIPPERS Specification of Iaetters Patent.

Patented June 1, 19 15.

Application filed January 12, 1915. Serial No. 1,825.

To all whom it may concern.

Be it known that I, WILLIAM G.'AoKnR- MAN, a citizen of the UnitedStates, residing at lVestpoint, in the county of Cuming and State ofNebraska, have invented certain new and useful Improvements inSharpeners for Hair-Clippers; and I do hereby declare the following tobe a full, clear, and eX- act description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a device -for sharpening the blades used inhair clippers, and the primary object of the invention is to provide asharpening device which will efficiently sharpen the blades used in ahair clip by the application of a whetting or sharpening stone to thesurface of the blades which engage each other, for evenly sharpening theentire surfaces of the blades for insuring the eflicient cuttingoperation thereof.

Another object of this invention is to pro vide a sharpener as specifiedwhich embodies a reciprocably movable sharpening stone, means forreciprocating the stone and for holding the clipper blade firmly uponthe upper surface of the sharpeningstone during the reciprocatorymovement of the stone for efficiently sharpening the blade.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters designate like orcorresponding parts throughout the several views, and in which Figure 1is a side elevation of the improved sharpener, Fig, 2 is a top plan viewof the sharpener showing parts thereof broken away, Fig. 3 is a verticalcross sectional view through the sharpener, Fig. 4 is a fragmentary topplan view of thesharpener, Fig. 5 1s a fragmentary vertical sectionalview through the sharpener, and Fig. 6 is a detail bottom perspectiveview of the clipper blade holding plate.

Referring more particularly to the drawings, 1 designates the supportingbase of the sharpener, which hasa vertical board 2 secured to the uppersurface at one end thereof, which board rotatably carries shafts 3 and4. The shaft 3 has a hand wheel 5 mounted thereupon, and also a gear 6which gear is rotated by the manual rotation of the hand wheel 5. Thegear 6 meshes with a plnlon 7 carried by the shaft 4, for rotating theshaft 4 by the rotation of the hand wheel and the shaft 3. The shaft 4has a disk 8 mounted thereupon, to which disk is eccentrically connecteda pitman rod 9. The pitman rod 9 extends longitudinally along the uppersurface of the supporting base 1,

being spaced upwardly therefrom, and has its rear end connected to aslidable block 10. The block 10 is slidably mounted upon the plates 11and 12, which plates are carried by suitable supporting legs 13'. Thelegs 13 are, in any way. desired, connected to the supporting base 1 andextend upwardly therefrom, as is clearly shown in Fig. 1 of the drawing.The plates 11 and 12 have their facing inner edges spaced from eachother for forming a guideway in which is seated the lug 13. The lug 13is formed upon and depends from the under surface of the slidable block10, and it guides the re ciprocatory movement of the block, preventingthe same from moving laterally during its longitudinal reciprocatorymovement. The block 10 also has a bolt 14 inserted therethrough, whichextends through the opening 15 formed by the spacing of the inner sideedges of the plates 11 and 12. The bolt 14 has a plate 15 secured to itsunder surface and held in slidable abutting engagement with the undersurfaces of the plates 11 and 12 by a nut 16 which is mountupon the endof the bolt. The plate 15 is provided for preventing verticaldisplaceduring the 20 and 21 into'engagement with the sides of asharpening stone 23, for holding the stone attached to the block 10 forslidable movement therewith.

The supporting structure or base 1 has a standard 24 secured thereto,which standard has an arm 25 pivotally connectd to its upper end. Thearm 25 has its outer end reduced and provided with a plurality of siwitha slot 30 formed in the upper face notches 26, for receiving a ring 27which is carried by a weight 28. The arm 25 has positioned therebeneath,a clipper blade engaging plate 29, which plate is provided structlon.

.Q Inthe o eration of the improved sharpcner heretofore described; theclipper blade to be sharpened, is placed upon the plate 29, after whichthelever or arm 25 is moved so that it will assume a horizontalpositionfand cause the under surface of the blade, which 1 is to besharpened to rest upon the upper surface of the sharpening stone 23. Theweight 28 which is hung upon the outer end of the arm 25 will tend toforce the blade against the upper surface of the stone for insuring thesharpening of the same upon the reciprocatbrymovement of the stone. Thestone 23 is reciprocated, by the rotation of the hand wheel 5 which willrotate the shaft 4. through the meshing engagement of the gear 6 and thepinion 7. The rotation of the shaft 4, will owing to the eccentricconnection between the piston rod 9 and the disk 8 reciprocate thesupporting block 10 and the whetting or sharpening stone 23, forsharpening the blade 32 of the clipper.

From the foregoing description taken in connection with the accompanyingdrawings the advantages of construction and ,of the method of operationof the improved sharpener for hair clippers will be readily apparent tothose skilled in the art to which this invention appertains and, whilein the foregoing description, the principle of the operation of thisinvention has been described together with various features ofconstruction, it is to be understood that certain minor features ofconstruction, combination andarrangement of parts may be altered to suitpractical conditions provided such alterations are comprehended withinthe scope of what is claimed.

What is claimed is 1. In a device for sharpening clipper blades, asupporting structure, a pair of horizontally disposed plates carried bysaid supporting structure and having their fac- W "ing sides spaced fromeach other, a block slidably' mountedtupon said plates, means forpreventing vertical and lateral movement of said block, a sharpeningstone detachably carried by said block, and-means for holding a clipperblade in engagement with the upper surface of said sharpening stone, andmeans for moving said sharpenmg stone'forwardly and rearwardly upon saidsupporting structure for sharpening said blade.

2. In a device for sharpening clipper blades, a supporting structure,yapair of -plates supported by said supporting structure and upwardlytherefrom, in a horizontal plane, said plates having their facing sidesspaced from each other, a block slidably mounted upon said plates, adepending lug formed upon said block and between the facing sides ofsaid plates for preventing the lateral movement thereof, means forpreventing vertical movement of said slot, at sharpening stonedetachably carried by said slot, a standard secured to said supportingstructure, an arm pivotally connected to said standard, a plate having aclipper blade detachably attached thereto, said plate having alongitudinal groove formed in the upper face thereof for receiving thelower edge of said arm for holding said clipper blade in engagement withthe upper surface of said sharpening stone, and means for moving saidsharpening stone forwardly and rearwardly upon said plate for sharpeningsaid cutter blade.

3. In a device for sharpening clipper blades, a supporting structure, apair of horizontally disposed plates supported by said supportingstructure and upwardly therefrom, said plates having their facing sidesspaced from each other, a block slidably mounted upon said plates, apair of upstanding plates carried bysaid block and provided for grippingthe side edges of the sharpening stone, means for tightening the grip ofsaid plates upon the sharpening stone, a standard carried by saidsupporting structure, an arm'pivotally carried by said standard, a platefor detachably supporting a clipper blade, said plate being providedwith a longitudinal groove for receiving the lower edge of said arm forholding said clipper blade upon the upper surface .of said sharpeningstone, a pitman rod connected to said block and means for reciprocatingsaid pitman rod for moving said block longitudinally upon said plate forsharpening the under surface of said stone, and means for preventingvertical and lateral movement of said block and said stone.

In testimony whereof I afiix my signature in presence of two witnesses.
